Globe Valve Bronze JIS 16K (Union Bonnet) - F7348

Bronze JIS 16K F7348 Union Bonnet Globe Valve

The JIS F7348 is a straight pattern globe valve with Union Bonnet construction, bronze body, and flanged ends to JIS 16K standard. Designed for manual isolation or throttling in small-bore marine piping systems where bonnet access is required for inspection or maintenance.

Test Pressures

Hydrostatic test pressures for F7348:

• Body: 3.3 MPa
• Seat: 2.42 MPa

Test pressures do not represent continuous operating pressure. Selection must consider pressure-temperature rating, media compatibility, temperature, and class society requirements.

Applications

• Auxiliary fresh water lines
• Service water (small bore)
• Oil lines (after material compatibility check)
• Low/medium pressure steam within design limits
• Locations requiring maintainable Union Bonnet

Difference from F7346

F7346 is a Union Bonnet globe valve to JIS 5K. F7348 is the straight pattern version for JIS 16K, with higher test pressures and different flange drilling. Do not substitute without verifying DN, flange type, face-to-face length, and design pressure.

Selection Considerations

Before procurement, confirm DN, JIS 16K flange compatibility, packing material, media, pressure, temperature, flow direction, and handwheel access. Standard version is manual; no actuator is specified in product documentation.
